The travelling Little Berries or when kids play up

An update on the boys' for those who are asking. So far, they have been to America (plane, car), Mexico (car, bus) and New Zealand (plane, car) in the space of 5 weeks. By now they have learnt the ettiquette of security clearances at airports, the "hold the crotch" joke at scanning, the importance of smiling when meeting air-stewardesses (or older, can't find a decent job,air- stewards) for extra freebies/food, critical seating by the window to alleviate boredom and how to wind parents up whilst driving long distances in the car.
Sebastian is learning that stubborness is something that will get him through even the toughest SAS initiation tests and Oscar knows that a simple physical slump to the ground will make even the hardest parent in the world concede.
Seba has complemented his obstinate stubborness with a foppish, dismissive wave of the hand and a cannot-care-less look around his shoulder. He generally knows that to use this in public (queing up, restaurants, etc) will generate the desired effect. Oscar, sensing that Seba is on to something, can't quite grasp the full routine so just slumps down on his arse with an ear-splitting "No!".
To be honest, this is relatively rare. They have been both good as gold. But they have superb timing when they fancy doing this stuff. Surreally, we have invented various parental diversion tactics. These are posted here for you to use - so feel free. One, a version of I-Spy which Seba has turned into a ragga-toasting version, "I an' I, with my litt'l spy". It is hilariously funny and one which I will torment him with for life. Second, with Oscar, I tell him a policeman or fierce dog is coming and this shifts him faster than the threat of a haircut. Marie informs me to try and not to do this in public as social services may see this as psychological abuse.
(Note - I realise that both may constitute some mild form of abuse but it's better than leaving them there and driving off which has crossed both our minds in quieter moments).
All in all though, the decision to take them on this trip was correct. Oscar has learnt to swim and his coversational skills are higher, Seba is more independent (umm,?), both have been up several mountains, eaten different foods and enjoyed them (made that one up), mined for gold, understand some of the differences between countries and language, can both talk about how honey is made in fine detail, have seen various regional variations of Hi-5 and Dora.
It has been easy taking them though. Only a few times has the 24-7 been too much but then we find a public park and they go wild for 30mins and then we're all re-charged.
Next stop in the next 4 days is to leave NZ and head for Oz and warmer climates.
